空城空巷空人心旧人旧梦旧心酸
[kōng chéng kōng xiàng kōng rén xīn jiù rén jiù mèng jiù xīn suān]
Translating to 'empty city, empty alley, the heart of an old man with old dreams feels old pain,' this nickname reflects a deep sense of emptiness and longing. It implies that even though things have changed, one's emotions remain tied to the past.
